mov_try_read_block is regularly
mov_try_read_block is regularly called with sizes such as 48 bytes,
but would allocate 1 MiB each time, hogging more and more memory
until playback ends.
Fixes #7641 and #9243.

Enable the checked bitreader to avoid overread.
Also add a few checks in loops and between blocks so we exit instead of
continued
execution.
Alternatively we could add manual checks so that no overread can happen. This
would be
slightly faster but a bit more work and

The two authored by me, the probe change is cosmetic, and the animation

Follow-up to [1], the decoder only.
In [1] we found a hanging sample. In frame-threading, this led to an
infinite wait, damaged frames otherwise. So warn acordingly and do
best-effort in single-thread mode.
Also split into more patches to make reviewing easier.

That is a good question. What other RIFF decoders are there for which
MSRLE support is important and depends on behavior different from VfW?
mpv and vlc work just fine.

Hi all,
just checking; do you consider this for merge into the upstream? It does
feel like a lot of upside without any downside.
Thanks
